Rays of light entering the eye are brought to a precise focus on the retina – the light sensitive layer lining the back of the eye. When such a focus is not achieved, a refractive error results and vision is not clear. These imperfections in the focusing power of the eye are called refractive errors.
Some people are born with refractive errors and some develop these refractive errors over time. The various reasons that cause changes in the refractive ability of the eye include the ageing process, physiological changes in body, stress, individual lifestyle like working on digital devices for long periods etc.
Poor quality of vision can disturb day to day activities and therefore eye tests done at regular periods can help address this issue. An eye Check Up helps determine the type of refractive error occurring in the eye and the means to correct the same.
Steps involved in an eye test:
1. BROAD FIRST POWER ASSESSMENT
Auto Refracto Keratometer, a Computerized eye test estimates optimal power of eyes
2. REVIEW OF PATIENT HISTORY
Evaluation through medical history for best suitable correction
3. CURRENT VISION TEST
Evaluation of Visual Acuity or the primary function of Eye called VISION
4. REQUIRED EYE CORRECTION TEST
Neutralization of eye reflex to estimate accurate refractive error utilizing the Retinoscopy technique
5. CONFIRMATION OF REQUIRED EYE CORRECTION
Prescriptive spectacles finalized through state of the art equipment, the Phoropter deriving the Subjective refraction
6. EXAMINATION OF EYE’S HEALTH
The Slit Lamp Examination provides a microscopic evaluation of structural details of the eye like the Cornea

What is the right way to do an eye test?An eye exam is a series of tests typically performed by an optometrist to check vision as well as structures and functions of the eye. The examination of the eye is of paramount importance in diagnosis of refractive condition of the eye. It needs to be done in a clinical environment with good lighting and at an optimal distance from the eye test chart.
How often should you do an eye test?Eye examination should be done once in a year, but in the case of systemic illness like diabetes , hypertension , thyroid etc it is ideally advised to get an eye test done every 6 months.
Eye Check Up for kids/senior citizens/people with ailments like diabetes, hypertension etc
Children should receive their first comprehensive eye examination before the age of 3, unless a specific condition or history of family childhood vision problems warrants an earlier examination.
Anyone with a history of visual problems should get routine preventive care.
Squinting, blinking, rubbing eyes frequently, headaches, changes in vision and difficulty with visual concentration within arm's length may be signs of eye problems and should be checked immediately by your optometrist.
